        <h1>TREND Function</h1>
        <p>The <b>TREND</b> function is one of the <a href="../UsageInstructions/InsertFunction.htm#statistical" onclick="onhyperlinkclick(this)">statistical functions</a>. It is used to calculate a linear trend line and returns values along it using the method of least squares.</p>
        <h3>Syntax</h3>
        <p><b><em>TREND(known_y’s, [known_x’s], [new_x’s], [const])</em></b></p>
        <p>The <b>TREND</b> function has the following arguments:</p>
        <table style="width: 40%">
            <tr>
                <th style="background-color: #f4f4f4" width="150ch"><b>Argument</b></th>
                <th style="background-color: #f4f4f4"><b>Description</b></th>
            </tr>
            <tr>
                <td><b><em>known_y’s</em></b></td>
                <td>The set of y-values you already know in the <em>y = mx + b</em> equation.</td>
            </tr>
            <tr>
                <td><b><em>known_x’s</em></b></td>
                <td>The optional set of x-values you might know in the <em>y = mx + b</em> equation.</td>
            </tr>
            <tr>
                <td><b><em>new_x’s</em></b></td>
                <td>The optional set of x-values you want y-values to be returned to.</td>
            </tr>
            <tr>
                <td><b><em>const</em></b></td>
                <td>An optional argument. It is a TRUE or FALSE value where TRUE or lack of the argument forces <em>b</em> to be calculated normally and FALSE sets <em>b</em> to 0 in the <em>y = mx + b</em> equation and m-values correspond with the <em>y = mx</em> equation.</td>
            </tr>
        </table>
